Abstract

The utility model provides a frame cross member forming mold. The frame cross member forming mold comprises a mold frame, wherein the mold frame is composed of a guide column guide sleeve assembly, an upper mold plate and a lower mold plate; a concave mold fixing plate is fixed to the lower mold plate; a concave mold embedding block is connected to the concave mold fixing plate; a convex mold fixing plate is fixed to the upper mold plate; a convex mold embedding block is connected to the convex mold fixing plate; an elastic blank holder is arranged in the periphery of the convex mold embedding block; a material ejector plate is arranged in the concave mold embedding block; both the concave mold embedding block and the convex mold embedding block are manufactured through berylco alloy; first guide blocks are arranged at two sides of the lower mold plate; second guide blocks are correspondingly arranged on the upper mold plate and matched with the first guide blocks to form an assist guiding device; a roller locating groove in which a rolling column is mounted is formed in a position at the upper plane of the concave groove fixing plate, corresponding to the elastic blank holder. According to the frame cross member forming mold, the surface of a formed frame cross member basically does not have any wrinkling and drawing stamp, the wall thickness is uniform, and the percent of pass is high.

Description

Frame cross shaping dies

Technical field

The utility model relates to the shaping dies of frame cross.

Background technology

As shown in Figure 1 and Figure 2, the cross section of frame cross 1 takes the shape of the letter U the structure of current a kind of frame cross, and the bending outline line of frame cross 1 is not straight line, has the first bending 1a and the second bending 1b, and bending outline line is three sections of broken lines; The guiding of conventional shaping dies is all to adopt guide pillar, guide pin bushing to coordinate guiding, and upper male mould and lower cavity die are all to adopt mould steel manufacture, when shaping, just blank are pressed in the upper plane of die by elastic blank holder; Due to, bending outline line is three sections of broken lines, causes blank to enter the mobile of lower cavity die and have some setbacks in forming process, trace is drawn on frame cross surface after shaping, particularly near the first bending 1a and the second bending 1b, easily wrinkling, draw trace serious, even also occur the phenomenon of breaking; Just adopt guide pillar, guide pin bushing to coordinate guiding, due to stressed asymmetric, also easily occur small inconsistent phenomenon, the frame cross wall unevenness after shaping is even.

Summary of the invention

In order to ensure that frame cross surface do not draw trace, the frame cross wall thickness after shaping is even, avoids occurring in the wrinkling and surperficial phenomenon of drawing trace of bending part of bending outline line, the utility model proposes frame cross shaping dies.

For this reason, the technical solution of the utility model is: frame cross shaping dies, comprise the mould bases that guide pillar guide pin bushing assembly, cope match-plate pattern, lower bolster form, on lower bolster, be fixed with die block, die plate insert is connected on die block, is fixed with punch retainer on cope match-plate pattern, and punch insert is connected on punch retainer, the outer elastic blank holder that is arranged with of punch insert, is provided with die pad in die plate insert;

It is characterized in that:

The material that die plate insert and punch insert adopt is beallon;

Both sides on lower bolster are respectively equipped with the first guide pad, and on cope match-plate pattern, correspondence is provided with the second guide pad, and the first guide pad and the second guide pad form auxiliary guide;

Upper plane at die block is provided with ball positioning groove corresponding to the position of elastic blank holder, and ball positioning groove is provided with roller.

Beneficial effect: the material that punch insert of the present utility model and die plate insert adopt is beallon, utilizes the characteristic of beallon can reduce surface wrinkling and draw trace phenomenon; Upper plane at die block arranges roller corresponding to the position of elastic blank holder, ensures that in forming process, blank flows smooth and easy; The setting of auxiliary guide, avoids occurring the small inconsistent phenomenon between punch insert and die plate insert, ensures that the frame cross wall thickness after being shaped is even.Adopt the frame cross surface after the utility model is shaped substantially do not have wrinkling and draw trace phenomenon, wall thickness is even, and qualification rate is high.

Detailed description of the invention

The utility model for frame cross be same or similar with the structure of the workshop crossbeam shown in Fig. 1 and Fig. 2.

As shown in Figure 3, further describe the utility model as follows: frame cross shaping dies, comprise the mould bases that guide pillar guide pin bushing assembly (guide pillar 3 and guide pin bushing 7), cope match-plate pattern 8, lower bolster 2 form, on lower bolster, be fixed with die block 14, die plate insert 13 is connected on die block 14, is fixed with punch retainer 6 on cope match-plate pattern, and punch insert 4 is connected on punch retainer, the outer elastic blank holder 5 that is arranged with of punch insert 4, is provided with die pad 10 in die plate insert 13;

The material that die plate insert 13 and punch insert 4 adopt is beallon;

Both sides on lower bolster are respectively equipped with the first guide pad 11, and on cope match-plate pattern, correspondence is provided with the second guide pad 9, the first guide pads 11 and the second guide pad 9 forms auxiliary guide;

Upper plane at die block 14 is provided with ball positioning groove corresponding to the position of elastic blank holder, and ball positioning groove is provided with roller 12.
